(Phys.org) -- Some materials, by their nature, do what we want them to do -- notably, the ubiquitous, semiconducting silicon found in almost every electronic device. But sometimes, naturally occurring materials need a little ...

TU Vienna has managed to turn the oscillation direction of beams of light – simply by applying an electrical current to a special material. This way, a transistor can be built that functions with light instead of electrical ...

Researchers at Wake Forest University's Organic Electronics group have come up with a novel solution to one of the biggest technological barriers facing the organic semiconductor industry today. Oana Jurchescu, an assistant ...

The propagation of the so-called 'magnetic fire' in certain systems seems to be "the only combustion process ruled by quantum laws known in the nature", points out Javier Tejada, Professor of Condensed Matter Physics at the ...

(Phys.org)—Individual electrons in graphene are massless, but when they move together, it's a different story. Graphene, a one-atom-thick carbon sheet, has taken the world of physics by storm—in part, because its electrons ...

Semiconductors have revolutionized computing because of their efficient control over the flow of electrical currents on a single chip, which has led to devices such as the transistor. Working towards a similar tunable functionality ...

Researchers from ETH Zurich and the Paul Scherrer Institute PSI demonstrate how the magnetic structure can be altered quickly in novel materials. The effect could be used in efficient hard drives of the future.
